    Yeah I had plans for something like that....
    But rather than over network I was going to have opensolaris (or some other spin, there are a few other options) in a VM sitting on a bare-metal hypervisor (native VMM) & the MythTV BE in another VM.
    But that was to be on a core i7 based system, & that's on hold for the moment...

      As much as I'd like a shiny new Clarkdale-based FE :lol:
      I'm starting to think it might make more sense to do an AIO?

        Well that's all a matter of opinion and what your planned future usage is. If you plan on having more then one htpc or not. There are also other items to consider what if you are recording something and need to reboot for what ever reason. I've never been a fan of using a workstation to pull server duties. Your chances of something going wrong increases with the risk of data loss. I have no problems with the kids using the htpcs or the workstations however I would have a huge issue with them trying to use the server for their games etc since running things like mame can often cause lockups etc where they would be tempted to reboot the system. Back to your system config however putting the 8600 card in the server is a waste at this point and would be better served in your htpc.

          He has got me thinking though...

          The money saved on not forking-out for new: CPU, Mobo, RAM, PSU, & local disk/disks, could go towards the current proposed BE for a: 30GB SSD(sell the 150GB Raptor), GT220(sell the 8600GTS), & 2GB extra RAM.

          Sure it'd be a bigger/louder machine, but overall it'd use less power & prolly cost the same as a BE & FE without an SSD.
          But what if I want to put in an extra HVR-2200, & swap-in a beefier GPU, I'm not sure it'd have enough room for everything?!

          Yeah but that depends on whether VDPAU definitely can't be harnessed for transcoding purposes. I know it's on the cards, just not sure if it's there yet.

            I think I'm going with an AIO, but with the FE I outlined as the platform base.

            So that means I'll sell most of the parts outlined for my proposed back-end.
            This will give me a little cash towards the new build, whilst allowing me to move to the newer/sexier Intel platform

            It'd be cheaper to go with the BE as the base for an AIO (& it'd be plenty of horsepower), but I prefer this approach.
            I'll outline the new machine I have in mind soon....

            As figrin mentioned Core i3-xxx VA-API support for acceleration is getting there, but still pretty rough.
            If I find it's not good enough after a few months, then I can always chuck in a GT220 to be used w/VDPAU.

            I do have plans later this year to build a Core i7-based native VMM (baremetal hypervisor).
            So this could become the BE & "jack of all" server, and the AIO could revert to a FE/occasional gaming machine.

            In the meantime I'll have my XBOX360 & soon a PS3 which can be used as FE's of sorts.
            PS3 in particular, now that it's "apparently" been fully hacked...

            Thanks for your thoughts thus far, any further ideas greatly appreciated!

            Goodnight.

                Here is the rough outline I have in mind, I already own parts that are in bold:

                1x Intel Core i3 530
                1x mATX H57 or Q57 mobo?
                2x 2GB DDR3?
                1x Asus Xonar Essence ST (PCI)
                1x Asus H6 (Essence daughterboard)
                1x Hauppauge HVR-2200
                1x Antec True Power 3.0 650W
                Storage Sub-sys:
                1x 30GB SSD? ................................... [boot/system volume]
                1x 1TB WD Black ..............................[capture disk, can it handle 4 simultaneous HD streams?]
                3x 1/1.5TB 7.2k HDD? .........................[For content storage & BU, may not bother w/RAID]
                __________
                Low priority
                **********
                1x HTPC Case? ................................... [Have crappy old Lian-Li (PC-60?) mid-tower]
                1x nV GT220? .................................... [only if IGP+CPU proves to be not enough]

                Make/model recommendations greatly appreciated!

                  What bit-rate is broadcast HD these days? I seem to remember that broadcasters are only using around 20Mbps, so I wouldn't imagine you'd have any trouble keeping up, particularly if you have lots of RAM for caching and a file system that doesn't sync all the time.

                    Yeah that's it, i was pretty sure i'd be heaps safe on this one, just wanted to check with others.
                    So any specific makes/models you'd throw in where I haven't mentioned any?

                    Do you think I'm going to have problems with this as an AIO when I start doing:
                    flagging, transcoding, 4 hd streams (2 play 2 record) BT dloads, playing media off storage disks etc.

                    Thanks!

                      My Atom does most of that without any real problems (except it only records one SD broadcast ad a time and transcoding is very slow), so an I3 with twice as much RAM should easily handle it.

                        has anyone heard of a h55/7 or q55/7 mATX mobo that has USB3/SATA6G?
                        I've only been able to find an ATX motherboard that meets those requirements: P7H57D-V EVO

                        come on ....
                        doesn't anyone have recommendations for makes/models?! ;-)

                          I would have suggested the WD Caviar Greens for the storage drives, but lately people have been saying they've had problems with the new versions; I'm not sure whether that's because they've switched to 4k sectors or whether there's something more inexplicable.

                            So the mobo is a toss-up between these 6 Gbyte's & Asus's

                            http://www.gigabyte.com.tw/Products/...08,3307&Page=1

                            http://www.asus.com/product.aspx?P_I...rsk&templete=2
                            http://www.asus.com/product.aspx?P_I...FyJ&templete=2
                            http://www.asus.com/product.aspx?P_I...N30&templete=2

                            Only 1 of the 6 has SATA6G and USB3, and it's ATX, such a downer...
                            Does anyone know of any H55/57 or Q55/57 mATX mobo's that have SATA6G & USB3?
                            I guess it gets trickier to implement....

                              Alas there's no Q5x/H5x mATX mobo's with SATA6G & USB3.
                              So it come down to these three:

                              GA-H57M-USB3 $174.0 [may be able to get for this price]
                              P7H55D-M EVO $179.3 [definitely can get for this price]
                              P7H57D-V EVO $292.6 [definitely can get for this price]

                              The last is ATX....
                              It does have SATA6G & USB3 but is substantially more than the other two.

                              I've realised that SATAII's "real world" limit is about 300MB/s anyway.
                              I'm not aware of any 30-40GB SSD's that could reach that limit, even at sustained read speeds.
                              So it's no big loss, when S6G does filter-down to H5x mATX boards, I can always sell & upgrade.

                              So these are my finalist parts (in AUD $):
                              *******************************************
                              approx $154 1x Intel Core i3-530
                              approx $179 1x GA-H57M-USB3 or P7H55D-M EVO
                              approx $145 G.Skill 2x 2GB DDR3 1600Mhz (PC-12800)
                              Storage Sub-sys:
                              approx $312 3x 1TB Samsung F3? ........................... [content storage & BU, may not bother w/RAID]
                              ___________
                              Total = $790
                              ---------------

                              Can I get some thoughts on this please!
                              Would you slot something different in?
